WILLIAM H. DELAMARE, OF DEPTFORD, ENGLAND.

IMPROVEMENT IN COTTON-SEED CLEANERS.

Specification forming part of Letters Patent No. 127,224, dated May 28,1872.

revolx'es within a hollow casing, the surface.

of said cylinder and the inner surface of the casing being metal, androughened bypunching or other means; and in combination therewith themeans for introducing and discharging the seed and the cotton fiber, aswill here inafter be more fully described.

In the accompanying drawing, Figure 1 represents a side elevation of themachine in section on the line a w of Fig. 2. Fig. 2 is a verticalcross-section taken on the line y y of Fig. 1.

Similar letters of reference indicate corresponding parts.

A represents a frame, which may be made of either wood or metal. B is acylinder or drum on the shaft (J, supported by journalboxes on theframe, as seen at D D. E E represent a driving and a loose pulley. Thesurface of the cylinder B is metal, and it is roughened by punching, sothat it is like a grater. There are various ways by which this may bedone, and I do not, therefore, confine myself to any particular mode. isthe easing, which is made in two or more concave parts, G being thelower part or semicircle, and H the upper part. This casing is made ofmetal, and is roughened the same as the cylinder. The casin g is placedconcentric with the cylinder, with a space, I, between the two of awidth greater than the greatest diameter of the cottonseed-say one-halfan inch or overso that in no case will the seed be crushed. J is thehopper, which extends nearly or quite the length of the cylinder,

which may be provided with a valve or slide,

worked automatically or otherwise, to regulate the quantity of seedintroduced and to intermit the flow of the seed, as may be desired. Onone side of the hopper or other part of the outer casin g, and forming aportion thereof,is a Wire-cloth screen, K, through which fibers ofcotton,- as they are torn from the seed, are discharged. L is anaperture or slot in the lower part of the casing for the discharge ofthe seed. It is closed by a slide or valve, M, and opened from time totime, as may be necessary, automatically or otherwise.

I The space I between the cylinder and the casing may be divided intotwo or more compartments by means of rings with roughened surfacesattached to the cylinder or to the casing, so that the seed may beoperated upon in one or all of the compartments at the same time.

I do not limit or confine myself to the precise form or arrangement ofthe parts described, as they may be varied in many ways withoutdeparting from my invention.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent- A revolving cylinder, B, provided with a"grater-formed surface, in combination with a stationary surroundingcase, H, having correspondin g grater-formed surface on'the inside, andthe screen K, as and for the purpose described. 1 I
